• quilted products were made in the past from natural materials such as cotton, wool, kapok, and feathers.
• natural materials such as cotton, wool, kapok, and feathers.
• chemical materials such as polyester fibers or the like.
• filling plies directly at starting from cables of chemical son by spreading of the filaments constituting these cables and treatment with a view to giving them bulk and cohesion.
• the new filling material according to the invention is based on fibrous material, and it is characterized in that it is in the form of an element of defined length, of small thickness compared to its width and its length. , consisting of a thread-like central core or edge, relatively dense and rigid in relation to the whole of the material, to which fibers orien ⁇ tees are attached substantially transversely to the core, entangled with one another, of so as to form a homogeneous veil, said fibers being arranged on either side of the core.
• This filling material imitating the natural feather can schematically be considered as constituted by a flexible filiform textile rod, on either side of which are distributed and to which adhere textile fibers forming barbs.
• the invention also relates to a method for producing such products.
• the method according to the invention consists, schematically, of forming in a known manner a fibrous sheet made up of fibers en ⁇ overlapped with one another, for example a cardboard or si ⁇ milary sheet, and is characterized in that one superimposed on the sheet thus formed and on at least one face thereof a plurality of spaced son based on a heat-bonding material, then provoking the connection of said spaced son with the sheet, which one then divides the sheet into strips on either side of the spaced wires, and finally cutting said strips to a determined length.
• the connection of the spaced wires with the sheet is obtained under the combined action of heat and pressure, for example by passing between two heating cylinders.
• the sheet is divided into strips by any suitable means; generally using a cutting means disposed on either side of the son.

• another means of separation is proposed, characterized in that, after bonding by heat / pressure of the spaced yarns on the fibrous web, the division into strips of the sheet obtained on either side of each yarn, is carried out naturally ⁇ Lement by tearing passing each of these in an eyelet, the fibers passing through the eyelet through which passes the wire to which they adhere most securely.
• the core is constituted by a wire based on fusible material, or which has been made fusible by coating.
• the textiles used are artificial and / or synthetic.
• the textile of the rod is either a monofilament or a multifilament, a double thread or sheathed with another thread; it may have a core / sheath structure, the latter being made of a polymer with a low melting point. It is also possible to deposit on the surface by coating or sheathing of the wire, a hot-melt type hot-melt product.
• this wire is formed by the assembly of two wires having different bonding points, for example one being based on an interpolyamide whose bonding point is close to 120 to 140 ° C, and the other based on polyamide 6-6.
• the wire of the rod can possibly be crimped or wavy.
• the fibrous material linked to the central core constituted by the above-mentioned thread is advantageously constituted by chemical fibers, such as polyester fibers, natural fibers, or artificial fibers, used alone or in the form of mixtures, of the same title or of different title, of the same section or of different sections, of the same cut or of different cut.
• chemical fibers such as polyester fibers, natural fibers, or artificial fibers, used alone or in the form of mixtures, of the same title or of different title, of the same section or of different sections, of the same cut or of different cut.
• the fusible wires are used which have undergone the silicone elaser type treatment, there may be difficulties in bonding the fusible wires; in this case, the latter, prior to their deposition on the fibrous web, continuously or discontinuously with this operation, are coated with silicone material and preferably dried around 180 ° C.
• the padding materials which are the subject of the present application may be of the same dimension or of different dimensions. It is thus that they can be of different length. They can also be of different widths; this is achieved by not spacing the wires regularly or by spacing them regularly but at spaces of different sizes. This gives a varied padding material, the mixture of products of different sizes can only provide more comfort.
• a light brushing can be carried out to ruffle the fibers and take away the unwanted superfluous fibers which are deposited on a cleaning roller of the known type in spinning.
• the brushing / cleaning operation can take place after cutting into strips before cutting into elements of defined length.
• FIG. 1 and 2 illustrate schematically in side view and in top view, a device for the production of the product according to the invention.
• the new packing material according to the invention is in the form of an element of defined length, of small thickness compared to its length, consisting essentially by a threadlike central core 1, relatively dense and rigid with respect to the whole of the material, to which are bonded fibers 2 oriented substantially transversely to this core 1, said fibers being entangled one to others and forming a homogeneous veil. These fibers 2 are arranged on either side of the core 1.
• a fibrous sheet 4 is produced in a bare manner, for example by means of a card, of a device. pneumatic Curlator type, or equivalent.
• a plurality of spaced apart fusible wires 6, superimposed for example from individual coils 5, are superimposed on this sheet 4.
• the wires 6 are regularly spaced on said sheet 4.
• heated rollers 7-8 causes the connection to the surface of the ply 4.
• This li ⁇ aison is obtained thanks to the heating rollers 7-8.
• these rollers exert a pressure which promotes the connection of the two constituents.

• Example 1 illustrates the present application without limiting it.
• the strips are formed by passing each wire through a round eyelet with a diameter of 15 mm, the fibers passing through the eye through which passes the wire with which they adhere best.
• the running speed of the assembly is 6 meters / minute; the strips thus produced have an average width of 15 to 20 mm.
